Problem with Samba using Service Pack 3

Okay, I am running NT 4.0 workstation with Service Pack 3 and I added the registry key to enable plain text passwords correctly and that worked fine. (I mean Samba worked at this point). However, a new problem arose. When I try to execute the devices applet in the control panel, I can hear the system do something, and then nothing. No process shows up in the Task Manger and nothing ever loads. If I remove the key from the registry and reboot it works fine again. Has anyone seen this problem?
